+# Vieter CLI
+
+I provide a simple CLI tool that currently only allows changing the Git
+repository API. Its usage is quite simple.
+
+First, you need to create a file in your home directory called `.vieterrc` with
+the following content:
+
+```toml
+address = "https://example.com"
+api_key = "your-api-key"
+```
+
+You can also use a different file or use environment variables, as described in
+[Configuration](/configuration).
+
+Now you're ready to use the CLI tool.
+
+## Usage
+
+* `vieter repos list` returns all repositories currently stored in the API.
+* `vieter repos add url branch repo arch...` adds the repository with the given
+  URL, branch, repo & arch to the API.
+* `vieter repos remove id` removes the repository with the given ID prefix.
+
+You can always check `vieter -help` or `vieter repos -help` for more
+information about the commands.

+{{< hint warning >}}
+**Important**  
+Because this project is still in heavy development, this documentation tries to
+follow the development branch & not the latest release. This means that the
+documentation might not be relevant anymore for the latest release.
+{{< /hint >}}
+
+## Overview
+
+Vieter has a few main features:
+
+* It's a simple & lightweight implementation of an Arch repository server
+* It allows for uploading of built package archives
+* It supports a basic build system to periodically re-build packages & upload
+  them to the server
+
+{{< hint info >}}
+**Note**  
+While I mention Vieter being an "Arch" repository server, it works with any
+distribution that uses Pacman as the package manager. I do recommend using a
+base docker image for your distribution if you wish to use the build system as
+well.
+{{< /hint >}}
+
+### Why?
+
+Vieter is my personal solution for a problem I've been facing for months:
+extremely long AUR package build times. I run EndeavourOS on both my laptops,
+one of which being a rather old MacBook Air. I really like being a beta-tester
+for projects & run development builds for multiple packages (nheko,
+newsflash...). The issue with this is that I have to regularly re-build these
+packages in order to stay up to date with development & these builds can take a
+really long time on the old MacBook. This project is a solution to that
+problem: instead of building the packages locally, I can build them
+automatically in the cloud & just download them whenever I update my system!
+Thanks to this solution, I'm able to shave 10-15 minutes off my update times,
+just from not having to compile everything every time there's an update.
+
+Besides this, it's also just really useful to have a repository server that you
+control & can upload your own packages to. For example, I package my st
+terminal using a CI pipeline & upload it to my repository!
+
+### Why V?
+
+I had been interested in learning V for a couple of months ever since I
+stumbled upon it by accident. It looked like a promising language & turned out
+to be very fun to use! It's fast & easy to learn, & it's a nice contrast with
+my usual Rust-based projects, which tend to get quite complex.
+
+I recommend checking out their [homepage](https://vlang.io/)!
+
+### What's with the name?
+
+Before deciding to write this project in V, I wrote a prototype in Python,
+called [Pieter](https://git.rustybever.be/Chewing_Bever/pieter). The name
+Pieter came from Pieter Post, the Dutch name for [Postname
+Pat](https://en.wikipedia.org/wiki/Postman_Pat). The idea was that the server
+"delivered packages", & a good friend of mine suggested the name. When I
+decided to switch over to Vieter, I changed the P (for Python) to a V, it
+seemed fitting.

+# API Reference
+
+All routes that return JSON use the following shape:
+
+```json
+{
+    "message": "some message",
+    "data": {}
+}
+```
+
+Here, data can be any JSON object, so it's not guaranteed to be a struct.
+
+### `GET /<repo>/<arch>/<filename>`
+
+This route serves the contents of a specific architecture' repo.
+
+If `<filename>` is one of `<repo>.db`, `<repo>.files`, `<repo>.db.tar.gz` or
+`<repo>.files.tar.gz`, it will serve the respective archive file from the
+repository.
+
+If `<filename>` contains `.pkg`, it assumes the request to be for a package
+archive & will serve that file from the specific arch-repo's package directory.
+
+Finally, if none of the above are true, Vieter assumes it  to be request for a
+package version's desc file & tries to serve this instead. This functionality
+is very useful for the build system for checking whether a package needs to be
+rebuilt or not.
+
+### `HEAD /<repo>/<arch>/<filename>`
+
+Behaves the same as the above route, but instead of returning actual data, it
+returns either 200 or 404, depending on whether the file exists. This route is
+used by the build system to determine whether a package needs to be rebuilt.
+
+### `POST /<repo>/publish`
+
+This route is used to upload packages to a repository. It requires the API
+key to be provided using the `X-Api-Key` HTTP header. Vieter will parse the
+package's contents & update the repository files accordingely. I find the
+easiest way to use this route is using cURL:
+
+```sh
+curl -XPOST -T "path-to-package.pkg.tar.zst" -H "X-API-KEY: your-api-key" https://example.com/somerepo/publish
+```
+
+Packages are automatically added to the correct arch-repo. If a package type is
+`any`, the package is added to the configured `default_arch`, as well as all
+already present arch-repos. To prevent unnecessary duplication of package
+files, these packages are shared between arch-repos' package directories using
+hard links.
+
+{{< hint info >}}
+**Note**  
+Vieter only supports uploading archives compressed using either gzip, zstd or
+xz at the moment.
+{{< /hint >}}
+
+## API
+
+All API routes require the API key to provided using the `X-Api-Key` header.
+Otherwise, they'll return a status code 401.
+
+### `GET /api/repos`
+
+Returns the current list of Git repositories.
+
+### `GET /api/repos/<id>`
+
+Get the information for the Git repo with the given ID.
+
+### `POST /api/repos?<url>&<branch>&<arch>&<repo>`
+
+Adds a new Git repository with the provided URL, Git branch & comma-separated
+list of architectures.
+
+### `DELETE /api/repos/<id>`
+
+Deletes the Git repository with the provided ID.
+
+### `PATCH /api/repos/<id>?<url>&<branch>&<arch>&<repo>`
+
+Updates the provided parameters for the repo with the given ID. All arguments
+are optional.

+# Builder
+
+Vieter supports a basic build system that allows you to build the packages
+defined using the Git repositories API by running `vieter build`. For
+configuration, see [here](/configuration#builder).
+
+## How it works
+
+The build system works in two stages. First it pulls down the
+`archlinux:latest` image from Docker Hub, runs `pacman -Syu` & configures a
+non-root build user. It then creates a new Docker image from this container.
+This is to prevent each build having to fully update the container's
+repositories. After the image has been created, each repository returned by
+`/api/repos` is built sequentially by starting up a new container with the
+previously created image as a base. Each container goes through the following steps:
+
+1. The repository is cloned
+2. `makepkg --nobuild --nodeps` is ran to update the `pkgver` variable inside
+   the `PKGBUILD` file
+3. A HEAD request is sent to the Vieter server to check whether the specific
+   version of the package is already present. If it is, the container exits.
+4. `makepkg` is ran with `MAKEFLAGS="-j\$(nproc)`
+5. Each produced package archive is uploaded to the Vieter instance's
+   repository, as defined in the API for that specific Git repo.
+
+## Cron image
+
+The Vieter Docker image contains crond & a cron config that runs `vieter build`
+every night at 3AM. This value is currently hardcoded, but I wish to change
+that down the line (work is in progress). There's also some other caveats you
+should be aware of, namely that the image should be run as root & that the
+healthcheck will always fail, so you might have to disable it. This boils down
+to the following docker-compose file:
+
+```yaml
+version: '3'
+
+services:
+  cron:
+    image: 'chewingbever/vieter:dev'
+    command: crond -f
+    user: root
+
+    healthcheck:
+      disable: true
+        
+    environment:
+      - 'VIETER_API_KEY=some-key'
+      - 'VIETER_ADDRESS=https://example.com'
+    volumes:
+      - '/var/run/docker.sock:/var/run/docker.sock'
+```
+
+Important to note is that the container also requires the host's Docker socket
+to be mounted as this is how it spawns the necessary containers, as well as a
+change to the container's command.

+# Configuration
+
+All vieter operations by default try to read in the TOML file `~/.vieterrc` for
+configuration. The location of this file can be changed by using the `-f` flag.
+
+If the above file doesn't exist or you wish to override some of its settings,
+configuration is also possible using environment variables. Every variable in
+the config file has a respective environment variable of the following form:
+say the variable is called `api_key`, then the respective environment variable
+would be `VIETER_API_KEY`. In essence, it's the variable in uppercase prepended
+with `VIETER_`.
+
+If a variable is both present in the config file & as an environment variable,
+the value in the environment variable is used.
+
+{{< hint info >}}
+**Note**  
+All environment variables can also be provided from a file by appending them
+with `_FILE`. This for example allows you to provide the API key from a docker
+secrets file.
+{{< /hint >}}
+
+## Modes
+
+The vieter binary can run in several "modes", indicated by the first argument
+passed to them. Each mode requires a different configuration.
+
+### Server
+
+* `log_level`: defines how much logs to show. Valid values are one of `FATAL`,
+  `ERROR`, `WARN`, `INFO` or `DEBUG`. Defaults to `WARN`
+* `log_file`: log file to write logs to. Defaults to `vieter.log` in the
+  current directory.
+* `pkg_dir`:  where Vieter should store the actual package archives.
+* `download_dir`: where Vieter should initially download uploaded files.
+* `api_key`: the API key to use when authenticating requests.
+* `repo_dir`: where Vieter should store the contents of the repository.
+* `repos_file`: JSON file where the list of Git repositories is saved
+* `default_arch`: architecture to always add packages of arch `any` to.
+
+{{< hint info >}}
+**Note**  
+Because Vieter hard links files between `download_dir` & `pkg_dir`, they need
+to be on the same file system.
+{{< /hint >}}
+
+### Builder
+
+* `api_key`: the API key to use when authenticating requests.
+* `address`: Base your URL of your Vieter instance, e.g. https://example.com
+* `base_image`: image to use when building a package. It should be an Archlinux
+  image. The default if not configured is `archlinux:base-devel`, but this
+  image only supports arm64. If you require aarch64 support as well, consider
+  using
+  [`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
+  ([GH](https://github.com/Menci/docker-archlinuxarm))
+

+# Installation
+
+## Docker
+
+Docker is the recommended way to install vieter. The images can be pulled from
+[`chewingbever/vieter`](https://hub.docker.com/r/chewingbever/vieter). You can
+either pull a release tag (e.g. `chewingbever/vieter:0.1.0-rc1`), or pull the
+`chewingbever/vieter:dev` tag. The latter is updated every time a new commit is
+pushed to the development branch. This branch will be the most up to date, but
+does not give any guarantees about stability, so beware!
+
+The simplest way to run the Docker image is using a plain Docker command:
+
+```sh
+docker run \
+    --rm \
+    -d \
+    -v /path/to/data:/data \
+    -e VIETER_API_KEY=changeme \
+    -e VIETER_DEFAULT_ARCH=x86_64 \
+    -p 8000:8000 \
+    chewingbever/vieter:dev
+```
+
+Here, you should change `/path/to/data` to the path on your host where you want
+vieter to store its files.
+
+The default configuration will store everything inside the `/data` directory.
+
+Inside the container, the Vieter server runs on port 8000. This port should be
+exposed to the public accordingely.
+
+For an overview of how to configure vieter & which environment variables can be
+used, see the [Configuration](/configuration) page.
+
+## Binary
+
+On the [releases](https://git.rustybever.be/Chewing_Bever/vieter/releases)
+page, you can find statically compiled binaries for all released versions. You
+can download the binary for your host's architecture & run it that way.
+
+For more information about configuring the binary, check out the
+[Configuration](/configuration) page.
+
+## Building from source
+
+Because the project is still in heavy development, it might be useful to build
+from source instead. Luckily, this process is very easy. You'll need make,
+libarchive & openssl; all of which should be present on an every-day Arch
+install. Then, after cloning the repository, you can use the following commands:
+
+```sh
+# Builds the compiler; should usually only be ran once. Vieter compiles using
+# the default compiler, but I maintain my own mirror to ensure nothing breaks
+# without me knowing.
+make v
+
+# Build vieter
+# Alternatively, use `make prod` to build the production build.
+make
+```
+{{< hint info >}}
+**Note**  
+My version of the V compiler is also available on my Vieter instance,
+https://arch.r8r.be. It's in the `vieter` repository, with the package being
+named `vieter-v`. The compiler is available for both x86_64 & aarch64.
+{{< /hint >}}
+
+## My Vieter instance
+
+Besides uploading development Docker images, my CI also publishes x86_64 &
+aarch64 packages to my personal Vieter instance, https://arch.r8r.be. If you'd
+like, you can use this repository as well by adding it to your Pacman
+configuration as described [here](/usage#configuring-pacman). Both the
+repository & the package are called `vieter`.

+# Usage
+
+## Starting the server
+
+To start a server, either install it using Docker (see
+[Installation](/installation)) or run it locally by executing `vieter
+server`. See [Configuration](/configuration) for more information about
+configuring the binary.
+
+## Multiple repositories
+
+Vieter works with multiple repositories. This means that a single Vieter server
+can serve multiple repositories in Pacman. It also automatically divides files
+with specific architectures among arch-repos. Arch-repos are the actual
+repositories you add to your `/etc/pacman.conf` file. See [Configuring
+Pacman](/usage#configuring-pacman) below for more info.
+
+## Adding packages
+
+Using Vieter is currently very simple. If you wish to add a package to Vieter,
+build it using makepkg & POST that file to the `/<repo>/publish` endpoint of
+your server. This will add the package to the repository. Authentification
+requires you to add the API key as the `X-Api-Key` header.
+
+All of this can be combined into a simple cURL call:
+
+```
+curl -XPOST -H "X-API-KEY: your-key" -T some-package.pkg.tar.zst https://example.com/somerepo/publish
+```
+
+`somerepo` is automatically created if it doesn't exist yet.
+
+## Configuring Pacman
+
+Configuring Pacman to use a Vieter instance is very simple. In your
+`/etc/pacman.conf` file, add the following lines:
+
+```
+[vieter]
+Server = https://example.com/$repo/$arch
+SigLevel = Optional
+```
+
+Here, you see two important placeholder variables. `$repo` is replaced by the
+name within the square brackets, which in this case would be `vieter`. `$arch`
+is replaced by the output of `uname -m`. Because Vieter supports multiple
+repositories & architectures per repository, using this notation makes sure you
+always use the correct endpoint for fetching files.
+
+I recommend placing this below all other repository entries, as the order
+decides which repository should be used if there's ever a naming conflict.
